PURPOSE: A photocurable composition is provided to be suitable for forming a resin cured layer with high refractivity and optical resistance, and to be suitable as an optical sheet assembly of a back light unit. CONSTITUTION: A photocurable composition comprises metal oxide particles in chemical formula 1: R_l Zr_m O_n, a UV-curable monomer, a photoinitiator, and additives. In chemical formula 1, R is metal selected from Y, Ca, Mg, and Ce, and l, m, and n is respectively an integer from 1-10,000. The crystalline phase of the metal oxide particles is at least one of cubic or tetragonal. The optical sheet comprises a cured resin layer formed by the photocurable composition. The refractive index of the cured resin layer is 1.54-2.0. |
